Copilot in Word can't read chat attachments; Word for web file picker shows “no token obtained”
Any news?

Nothing from Microsoft. I tried the solution from DadBeatDead with the "/", and it worked with one file. So maybe there is hope.
The whole thing is an annoyance, though probably not a deal-breaker, at least not yet. In my work as a patent lawyer, I frequently have to deal with multiple files that need to be uploaded, for the AI to get all the data - e.g., prior art publications, USPTO office actions, specification and figures, fillable forms, that sort of thing. Can I have M365 Copilot do the work, and then copy-paste it into a Word file, and then work with Word Copilot going forward? Sure. But it is an annoyance.
Maybe when I become more proficient with AI, and I am ready to try things I haven't done yet, like Claude or OpenClaw or whatever, I'll end up switching to a different AI platform.

What seems to be working for me, albeit intermittently but still more than say 60% of the time, is I upload a file through Word Copilot, tell it to do something, it then thinks for a while and returns the "can't read/file empty/corrupted" error.
I then hit "/", the file I just uploaded shows up, I select that, copy my previous prompt and HEY PRESTO! the file is not empty/corrupted.
Fingers crossed this has been working quite well for me (one more step but it is really inconsequential to my workflow given how much time Copilot saves me).
One thing: I have not touched my OneDrive in a while. I usually clean up the files regularly, but have not muddled with OneDrive other than uploading files through Word Copilot. I am not sure if this provides any useful diagnostic information, or if it is more coincidence than causative, but just thought I would mention it.
Of course on the odd occasion hitting "/" doesn't show any files and then I close everything, restart, sacrifice a small animal, burn incense, turn salt and hope for the best...

Thanks - I tried it with one file, seemed to work.
I generally do work that requires file upload in M365, then tell it to give me a link for download of the MS Word file with the generated output, then use the file with Word Copilot.
Annoying, but... sort of works for now.

Nada.
I've gotten used to switching between M365 Copilot (where file upload works) and Word Copilot, where it doesn't.

Same here, but it used to be very convenient. Unfortunate development. Many users might switch to anther provider.
